An Organ‐on‐Chip Platform for Strain‐Controlled, Tissue‐Specific Compression of Cartilage and Mineralized Osteochondral Interface to Study Mechanical Overloading in Osteoarthritis

open access: yesAdvanced Healthcare Materials, EarlyView.
A mechanically active OsteoChondral Unit (OCU)‐on‐Chip platform mimicking the OCU's functional anatomy and the strain gradient across the osteochondral interface is presented. Upon compartment‐specific hyperphysiological compression, the model replicates mechanisms observed in osteoarthritis (OA) progression, such as calcium crystal accumulation ...

Age dependent sensitivity of the rat retina to the excitotoxic action ofN-methyl-D-aspartate

open access: yesNeurobiology of Disease, 1995
We have found that the rat retina can be isolated atraumatically and incubatedex vivofor up to 24 h without showing signs of histological deterioration, and that retinas from adult or aged rats can be isolated as successfully as those from immature rats.

Glutamate and GABA [PDF]

open access: yesNeuron, 2001
Regulation of release of inhibitory neurotransmitter is a key element of plasticity in dorsal horn function. In this issue of Neuron, Kerchner et al. report that neurotransmitter release from inhibitory dorsal horn neurons is affected by activation of presynaptic kainate-type glutamate receptors.

State‐of‐the‐Art, Insights, and Perspectives for MOFs‐Nanocomposites and MOF‐Derived (Nano)Materials

open access: yesAdvanced Materials, EarlyView.
Different approaches to MOF‐NP composite formation, such as ship‐in‐a‐bottle, bottle‐around‐the‐ship and in situ one‐step synthesis, are used. Owing to synergistic effects, the advantageous features of the components of the composites are beneficially combined, and their individual drawbacks are mitigated.

Neurobiology of Kleptomania: an overview

open access: yesSri Lanka Journal of Psychiatry, 2014
Kleptomania is a psychiatric manifestation frequently encountered in neurological conditions, especially Parkinson’s disease. This disorder has traditionally been considered to be a part of the obsessive compulsive spectrum disorder, but recently the ...

A Multifunctional Binder for Current‐Collector‐Free Zn Powder Anodes

open access: yesAdvanced Materials, EarlyView.
By introducing abundant polar groups as Zn2+ absorption sites and hydrogen bond arrays, a protein structure‐derived binder for ZP anode and iodine cathode is proposed. This design can regulate the Zn2+ flux, benefit the formation of free‐standing electrode, inhibit the side reactions, suppress the shuttle effect of polyiodides, and enable the large ...

Chronic cocaine enhances release of neuroprotective amino acid taurine: a microdialysis study [PDF]

open access: yes, 2008
Cocaine inhibits high-affinity neurotransmitter uptake at the presynaptic nerve terminals to increase synaptic levels of dopamine, norepinephrine and serotonin^1^. This increase of synaptic dopamine may cause neurotoxicity^2,3^.

An Ultrapotent, Ultraeconomical, Antifreeze Polypeptide

open access: yesAdvanced Materials, EarlyView.
Simple and inexpensive polypeptides composed of random copolymers of alanine and glutamic acid are effective antifreezes for applications in foods and biomedicine. The polypeptides, inspired by natural extremophile proteins, inhibit the growth of large ice crystals and prevent damage to sensitive biologics.
